The following simplified conversion factors are accurate to within 2 percent for quick computations:a. Inches to centimeters - Multiply inches by 10 and divide by 4.b. Yards to meters - Multiply yards by 9 and divide by 10.c. Miles to kilometers - Multiply miles by 8 and divide by 5.d. Pounds to kilograms - Multiply pounds by 5 and divide by 11.7. The following conversions are provided for guidance when procuring lumber, wire rope, or wire in areasthat use the metric system. Lumber sizes are rounded off to the nearest 1/2 cm.a. Lumber2-in x 4-in x desired length = 5-cm x 10-cm x desired length1-in x 6-in x desired length = 2.5-cm x 15-cm x desired length6-in x 8-in x desired length = 15-cm x 20-cm x desired length1-in x 12-in x desired length = 2.5-cm x 30-cm x desired length (length normally expressed in ft or m)b.
